After analyzing the intrinsic properties of the network coding, we consider the problem of minimizing the resource used for linear network coding while achieving the maximum multicast rate. Since this problem is NP-hard, we propose an improved genetic algorithm that works in an algebraic framework, combined with randomized polynomial identity testing methods, which reduces the number of nodes participating...
Delay tolerant networks (DTNs) use a store-carry-forward communication model relying on the mobility of nodes because a persistent end-to-end path from source to destination generally does not exist. Epidemic routing is a typical protocol in which data can be replicated along multiple opportunistic paths. With the advent of network coding, it is intuitive that data can not only be replicated, but...
With the success of P2P file sharing application and the development of multimedia coding technique, IPTV, a new emerging P2P application, arises on the Internet for streaming content. In order to gain insights into P2P IPTV systems, we have undertaken an in-depth measurement study of one of the most popular IPTV systems, namely UUSee, compared with BT-like file sharing application. The measurement...
Network coding is a promising technique to improve the resource efficiency and reliability for multicast networks. With network coding, each node of the multicast network is able to generate and transmit encoded data of information. This paper proposes a deterministic linear network coding scheme. This scheme exploits a special type of network topology called uniform network. This network structure...
This paper proposes a novel framework for the compression and transmission of the auto-stereo video. Based on the video-plus-depth data representation, this framework provides high adaptability, reliability and flexibility for the stereo display. Besides, it also permits the consumers to be interactive with the perception of the stereo video. The proposed compression approach for the video-plus-depth...
